Application tiled September 30, 1922. Serial No. 591,458.

` o all whom it may concern.'

Be it known that I, LESTER CLIFTON Ron, citizen of the United States, residing at ayside, Long Island, New York, in the ounty of Queens, State of New York, have nvented certain new and useful Improvei ents in Heaters, of which the following is full, clear, concise, and exact description.

This invention relates to heaters and aricularly to devices for heating dwel ing l ouses.

The object of the invention is to produce eiicient, easily maintained and simply egulated combined floor heater and water I eater.

A feature of the invention resides in the ombination of a pipeless hot air furnace with a water heater. According to this featurea water heater of novel design is lsurrounded bya heating chamber which in turn is surrounded by a hot air flue and which again in turn is surrounded by a return cool air chamber.

vention, the heater is constructed of sectionalized parts whereby without changing the design, the heater may be assembled in a unit of any desired capacity.

According to a further feature of this invention, the water heating unit is adapted to be used without change either to generate steam for supply to the radiator system of a building or to heat water for circulation through the radiator system.

A still further feature of the lnvention resides in the means for supplying heat. The preferred embodiment of the invention embraces a gas burner, but provision is made to employ other burners of substantially similar shape and size which are desiglned to burn kerosene, coal oil, crude oil, alco ol or other available fuels of like nature.

Other features of this invention will appear hereinafter.

In the drawings Fig. 1 is a view 'of the heater forming the subject matter of this application, partly, in section taken on a vertical plane passing through the axis of the device, Fig. 2 is a to View looking down, Fig. V3 is a sectiona view taken on the line.3, 3, and Fig. 4 is a detail view representing a burner adapted to utilize liquid fuel instead of as.

Set into the oor 1 is the outer shell 2 of the heater and 'set on top of the outer According to another feature of this inshell 2 and flush with the floor 1 is a register grating 4. Secured to the shell 2 are a pluralit of sup orting legs 5 reaching from the ttom ci) the heater to the ioor below and which may be adjusted as to length during the installation of the heater to suit the varying conditions encountered.

Secured to the outer shell 2 and a suitable distance above the point at which the supporting legs 5 are secured are a plurality of supporting brackets 6 on whlch an inner shell 7 is placed.

The supporting legs 5 are substantially of an inverted U shape and to the inner legs thereof is secured a cylindrical member -8 having a number of inwardly pro'ecting bracket arms 9 forming the support or the base casting 10, substantially the shape of the frustum of a cone. Between the bracket arms 9 and the base casting 10 at the several points of support are inserted the supporting members 11 secured to and serving to uphold the burner cone 12.

Resting on the base casting 1() and secured thereto is a water chamber casting 13, which together with a casting 14 forms one unit water chamber. In the present disclosure three such units are shown, consisting of three interchangeable bottom portions 13, 15 and 17, and three interchangeable upper ortions 14, 16 and 18. These portions may bolted together and made water tight by the use of suitable gaskets at the joints. Though but three units have been shown it is apparent that any number may be used that space will permit and varying conditions may require.

Resting on the base casting 10 and secured thereto 1s a corrugated sheet metal heat chamber shell 19 surrounding the water chamber casting 13 and conforming in general shape therewith. Secured to the top of shell 19 is a shell 20 completing a unit of the heat chamber. Shells 21 and 23 are similar to and interchangeable with shell 19 and shells 22 and 24 are similar to and interchangeable with shell 20.

Supported on top of the shell 24 by suitable legs 25 is a water receptacle 26 by means of which a small amount lof moisture is added 'to the dry warm air currents rising from around the outside of the heat chamber shells through the register 4. 'Secured to the uppermost 'shell 24 is a flue 27 leading through a suitable sheet metal elbow 28 to a pipe 29 whereby the gaseous products of combustion may be directed into a'chimney.

Resting onl top of the legs 5 is a fiat ring shaped piece lof sheet metal 30 designed to' revent air currents from underthe heater rom risino' in the air heating space with-l in the shell 7. On top of this is another ring shaped piece of sheet metal 31 which is substantially of an inve'tedU shape in section and which is perforated with a large number of holes and designed to distribute fresh air led thereinto through the duct 32.

A pipe 33 leads from the top of the uppermost water chamber unit 18 to the radiator system of the house and a pipe 34 leads from the bottom of the lowermost unit 13, where a connection is made to asupply pipe 35 and a drain cock 36. A pipe connection 37 is made between the top plpe 33 and the bottom pipe 34 and serves as a means for mounting a water level gauge glass 38 and such other necessary instruments as a safety valve 39 and a pressure gauge 40. l

In case this heatery is used to supply a steam radiator system the water level gauge glass 38, the safety valve 39 and the steam pressure gauge 40 are employed. In case the heater is used to supplyhot Water to a hot water radiator system, then those instrumentsl are not installed but instead a water level indicator similar in appearance to the steam pressure gauge 40 is employed and a return pipe 41 is added.

Supported within -the burner cone 12 a ring shaped burner 42 through the center of whlch the pipe 34 passes. The burner 42 is supplied with a mixture of gas and air through the pipe 43, the mixing taking place outside the heater at the fiared end 44 of the pipe 43. Gas is supplied through the servlce .pipe 45 and the feed is controlled by a valve 46.

Unregulated by the valve 46 is a small pipe connection 47 serving a pilot light. The. valve 46 may be adjusted from the floor above byemploying a socket key fitting over the squared end 48 of the rod 49. Several prongs von the end of the rod 49-engage the spokes of the handle 50 of valve 46 so that a connection similar in principle to a universal joint is formed.

A rod 51, squared at the end is employed to regulate a valve 52 to-control the supply of fresh air.

lVhen the heater lis in operation and the gas and airmixture is issuing from the burner 42, the hot gases rise through the top of the burner cone 12, pass through openings in the base casting 10. surround the water compartment units and finally pass out of the flue 27. The water within the water compartment units is brought up to the desired temperature and the degree of heat is regulated from the floor above by manipulating the valve rod 49. At the same time the shells surrounding the water compartment units are heated and serve as a means to cause air currents to rise and pass through the register grating 4 to heatthe room above the fioor 1. Cold air currents descend through the outer portion of the grating 4, pass downwardly between the outer shell 2 and the inner shell 7 and enter the hot air compartment atlthe bottom thereof. One advantage of this arrangement is that the outside olf-5 the heater is always cool and no heat is lost in the cellar or room where the heater is installed.

This heater may be used as a floor heater or pipeless hot air furnace alone by omitting the installation of the water connecttions and the connections to a radiator system, or if such are installed by draining the water from the water compartment units. In this case those: units serve as bafiies to direct the hot gases against the shells 19 to 24. Through the corrugated surfaces and the peculiar form of the shells 19 .to 24 a very eflicientheatino' surface is presented and it has' been found that a heater of this design will operate at a very low cost.

In Fig. 4 a conventional form of liquid fuel burner in size and general shape similar to the gas burner 42, connected to a liquid fuel storage tank 54 is shown. The particular design of the liquid fuel burner forms no part of the present invention as the use of any Well known and efficient burner is here contemplated.
